This is the VM11 Vision Module #A-5378-0087.
VM11 vision module
The VM11 vision module can be used for inspecting features or holes that are typically 0.4 mm or larger, with a maximum field of view of 10 mm × 12.5 mm. Typical applications for the VM11 module include laser drilled cooling holes in aerospace engine blades and components.
Stand-off is described as the distance required between the bottom of the vision module and the part feature to ensure optimum metrology performance.
Both vision modules have different stand-off distances to allow the inspection of a variety of parts. The stand-off distance for the VM11 module is 120 mm.
VM11 field of view
The field of view for each vision module determines the size of feature than can be inspected using a single exposure when the RVP system is at the correct stand-off distance.
The VM11 field of view is 12.5 mm × 10 mm; any feature that requires inspection must be within these dimensions to be captured with a single exposure.
